With the Season 4 Premiere of Game of Thrones just over one month away, HBO has debuted five character posters featuring the Lannister family, Tyrion (Peter Dinklage), Cersei (Lena Headey), Jamie (Nikolaj Coster-Waldau), King Joffrey (Jack Gleeson) and Tywin (Charles Dance). These images also feature the phrase "valar morghulis," which translates into "all men must die" in the High Valyrian language, and was also the title of the Season 2 finale. Does this mean that some of the Lannister's will not make it to the end of Season 4 (or the inevitable Season 5)? In addition, we also have a brief teaser video featuring Tyrion being held captive. Stay tuned for more posters and videos as we get closer and closer to this hit series returning Sunday, April 6 at 9 PM ET on HBO.
